Title: Improvements in or relating to the purification of penicillin
Filed: 1947-11-12
Abstract: Penicillin is purified by treating a solution of impure penicillin in a water-immiscible, non-polar organic solvent (e.g. amyl acetate, chloroform or ether) with about 25 per cent to about 5 per cent of an adsorbing agent such as active carbon, fuller's earth, silica gel or aluminium oxide and separating the adsorbent together with the adsorbed impurities.  Preferably 0.25 to 3 per cent w./v. and more desirably 0.25 to 1 per cent w./v. of adsorbent is used.  In examples: (1) penicillin in amyl acetate is purified by addition of activated carbon and is converted to its calcium salt; (2) penicillin is purified as in (1) and converted to the sodium salt; (3), (4) and (5) penicillin in chloroform is purified with activated carbon as in (2); (6) fuller's earth is used as the adsorbent in the processes (1)-(5); (7) alumina is used as the adsorbent in the processes (1)-(5).

Title: Improvements in or relating to electric protective arrangements
IPC: H02H3/30
Filed: 1926-12-03
Abstract: 285,194. Callender's Cable & Construction Co., Ltd., and Kibblewhite, C. Dec. 3, 1926. Cut-out arrangements.-In balanced protective systems employing current transformers in order to avoid undesired operation due to inherent differences in the transformers which reveal themselves with heavy straight through overloads, the transformers are designed so as to be saturated or nearly saturated at normal load currents and to have identical characteristics up to the saturation point. In order to ensure protection against every form of fault with such transformers they are wound on the primary side with different numbers of turns in each phase so that the effect of a fault in the protected circuit is to cause a large phase displacement of the resultant flux in the transformer core or cores at one end and thus disturb the balance. Two or more transformers at each end with each a different allotment of turns in the several phases will ensure that there is a resultant main flux in one or other of the cores which is out of phase with all of the flux components corresponding to the various phases. The arrangement affording protection of the Merz-Price type is shown in Fig. 1. Current transformer A of the ring type is passed by three turns of phase D', one turn in the same direction of phase D<2> and one turn in the opposite direction of phase D<3>. Transformers B, C are passes by numbers of turns in the different phases in directions which differ from one another and from transformer A as indicated in the drawing. The secondaries are connected (through three relays at each end) to the secondaries of similar and similarly-wound transformers at the other end. The resultant field in each of the three cores A, B, C is out of phase with all of the fields produced by the individual phases and the three resultants are 120‹ out of phase with one another thereby permitting the interconnection of the secondaries in star, as shown. An arrangement is described also in which two current transformers at each end (instead of three) are employed. The application to fan inductor protection of a three-phase system (see Specification 162,828), in which one of the phases is split and taken through a current transformer and, together with the unsplit phases (with different allotments of turns for each phase), through two balancing transformers which are easily saturated is described also.
